My parents remodeled our house and I wound up in a bedroom that joined our bathroom. As a 13 or 14 year old boy my dick was hard most of the time and I was always looking for something to masturbate to. One day I was in my bedroom when I noticed the bathroom light came on. I could see light coming through the key hole. I quietly eased over to the door and looked through the hole. It was my oldest sister. She was probably 17 at the time, a little chunky bot not huge, but boy did she have some amazing big tits. I watched her as she undressed and got into the shower. While she was in the shower I stood up and began to stroke my cock thinking about her hairy pussy and those big tits. When I heard the shower stop I peeked back through the hole just as she was stepping out of the shower. She looked amazing, her pussy hair was wet and clung tight to her body and her tits were red from the hot water washing over them. I was amazed and horny as hell looking at her body. As I watched her I was slowly stroking myself and wanting to cum oh so badly, but I couldn't stop watching long enough to stand up and finins. As I watched her she moved over to the sink which was closer to my door. She was so close now that I thought she would hear me breathing but I couldn't walk away now. She was standing not 2 feet away from me naked as hell and I was loving every minute of it. This is when things started to go wrong. She turned and grabbed a towel and before I knew it she was opening my bedroom door. I was caught red handed. Here I was with my pants down around my ankles and my cock in my hand when she came through the door. I didn't know she liked to use my dresser mirror to do her hair. Anyway, as she entered my room I knew I was in trouble. She stopped the minute she saw me and asked what the heck I was doing. I couldn't say a word, all I could do was stand there with my dick in my hand. I managed to say please don't tell and that I would never do it again. She just stood there looking at me holding my dick in my hand. She said she was going to tell on me but I begged her not to. I told her I would do anything she wanted if she didn't tell. She asked me if I would do her chores for the rest of the week, I eagerly said yes. Then she asked if I would wash her car, again I said yes. All of this time she was still looking at me holding my dick in my hand. I was still hard and by now the head of my dick was purple because I was squeezing it so hard. That was when she asked me what I was thinking about while I played with myself. I didn't know if I should tell her the truth or not. I decided to tell her and when she realized I had been looking at her I thought she was going to run tell right then. But she didn't. She asked me if I was close to cmming and I said that I was. That is when she told me to finish while she watched. I was floored, I had never done anything like that before. But I found myself stroking my shaft while watching her watch me. I stepped back to the bed and sat down on the edge. She moved closer to me and was fixated on my hand and cock. She bent down to get a closer look and her towel fell open and I was again seeing her tits. She didn't try to cover herself. I was stroking fast and starting to get close when she asked if she could touch it. Of course I let her. She reached down and just barely touched the tip of my dick. She said it felt so hot. I said touch it again and removed my hand from it. She gently grabbed my shaft and gave it a squeeze. When she did my cock twitched and she jerked her hand back. It was then that I began to realize that she had never played with a cock before. I let her do what she wanted to it for a while before asking her if she wanted to suck it. She didn't and asked me to play with it some more. As I started stroking it again I told her to drop her towel. She let it fall and now I was within a few inches of her and her hairy virgin pussy. I reached out and ran my hand up het leg to her pussy and found out that she was soaking wet. I slid my finger between her juicy lips and gently slid it inside her. I didn't go deep but she did moan a little. All the while she was watching me stroke my cock. I knew I was getting close so I told her to kneel down in front of me. When she did I told her to spit on the head of my dick. I used her spit as lube and started stroking faster and faster. Just as I was about to cum I told her to spit again and just as she started to spit I came. The first squirt hit her on the chin but the second one went in her mouth. She jumped back but almost immediately leaned back over my cock. As I was slowing my strokes I told her to kiss the head of my dick. She leaned down and kissed just the tip of it. I told her to take the head in her mouth which she did. After a few seconds she was sucking every last drop of cum off of and out of my dick. She sucked me for a couple of minutes before I mentioned she might want to get dresse before someone comes by. That was a great experience but it wasn't the last one with her.
